| Objective: To observe the clinical efficacy of injection of triangular space of rotator cuff under the guidance of ultrasound combined with conventional rehabilitation techniques in the treatment of partial and full thickness small tear rotator cuff injury. Methods: 128 patients with partial and full thickness small tear rotator cuff injury were randomly divided into control group (42 cases), pain point injection group (43 cases) and ultrasound guided injection group (43 cases). All three groups received routine rehabilitation treatment, pain point injection group was treated with local pain point injection of the shoulder joint, and ultrasound injection group was treated with injection of triangular space of rotator cuff under the guidance of ultrasound. Visual analogy scale score (VAS), Constant Murley shoulder score system (CMS) score and self care ability score in functional independence measure (FIM) were compared before and 3 weeks after treatment. The total effective rate of clinical treatment among the three groups was compared. Results: After 3 weeks of treatment, the VAS scores in the three groups were significantly lower than those before treatment (all P<0.01), those in the pain point injection group and ultrasonic injection group were lower than those in the control group (both P<0.05), and those in the ultrasonic injection group were lower than those in the pain point injection group (P<0.05). The CMS scores and FIM self care ability scores in the three groups were significantly higher than those before treatment (all P<0.01), those in the pain point injection group and ultrasonic injection group were higher than those in the control group (all P<0.05), and those in the ultrasonic injection group were higher than those in the pain point injection group (P<0.05). The total effective rate in the pain point injection group and ultrasonic injection group was significantly higher than that in the control group (both P<0.05), and that in the ultrasonic injection group was higher than that in the pain point injection group (P<0.05).Conclusion: Compared with pain point injection combined with conventional rehabilitation technology, injection of triangular space of rotator cuff under the guidance of ultrasound combined with conventional rehabilitation technology can significantly alleviate the clinical symptoms, improve the function of shoulder joint and the ability of daily life of patients, and exert better effects. |
